Hair Follicle Drug Testing - Silvana, WA

What it is, How it works

Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair retains a historical record of drug and alcohol use because biomarkers are deposited within the hair as it grows. Collected at the scalp, hair samples can reveal a detection period of up to three months for drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and simple to transport.

A hair sample of 1.5 inches containing around 200 strands (comparable to a #2 pencil) taken from the scalp area provides 100mg, which is optimal for screening and confirmation purposes. For EtG testing, additional tests, or panels exceeding 10, a sample of 150mg is advisable. We suggest using a jeweler's scale to weigh the specimen. If scalp hair is unavailable, a similar quantity of body hair can be obtained as a substitute. When referring to head hair, we mean scalp hair exclusively. Body hair includes all other types (such as facial and axillary hair).

Process Overview

The drug test results are processed through four main stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is logged into the laboratory's system. This involves checking that the sample is properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and entering additional data not captured via electronic chain of custody.

Screening provides an initial assessment for drugs of abuse. Though a budget-friendly way to exclude drug usage for most samples, positive screens must be confirmed for legal purposes. Samples indicating possible positive results in Screening require further verification.

In cases of presumed positive results during Screening, additional hair is taken from the original sample for Extraction. This stage extracts drugs from hair in much lower concentrations than other methodologies (such as urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of a positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with probable positive outcomes are washed as part of the confirmation process if needed. The entire process, from Accessioning to Confirmation, is conducted following CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a shorter detection timeline.
• Hard to falsify: Hair drug tests are very challenging to manipulate, yielding more reliable results.
• Reveals historical use: It can display a usage pattern of drugs over time, rather than merely showing recent consumption.

Limitations:

• Cannot identify recent use: It takes roughly 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences may influence the level of drug metabolites in the hair.

Note: Despite the term "hair follicle test," the analysis is conducted on the hair strand, not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.

In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
